The ending of this (intended) thriller is the rock bottom of depressing, but since it's based on true events (or so they claim), I probably cannot blame the makers for this. I can, however, blame them for all the rest. Because this movie really is, in everything that matters, below every par!
The acting of the whole cast is terrible - are they even actors?! The score is irritating, and the whole movie looks like it's filmed with a handheld smartphone. All member of the besieged family are unsympathetic to begin with: the mother is an hysterical ADHD, daughter Jill is a cranky btch, and daughter Megan a sullen dope. The stalking psycho-ex looks like a babyfaced teen with a tantrum and a lisp. Why didn't the three at the start of their ordeal jump in the car and drive the hell out of there, in stead of just calling 911 and going back into the house?! And there were countless moments when they could easily have thrown themselves on top of this guy - like in the end when he took forever to drown Jill in the pool, and Megan stands totally passive, just speechless and appalled, behind his back!
Anyway, the whole project breathes low (to no) budget and amateurism. I sat the whole thing out, just to see the psycho-ex get his comeuppance, but they even denied me that satisfaction. In short: a probably well-meant, but totally failed wannabe thriller.
